It's fatigue, but better. I wanted to make a more interesting card advantage card than just another divination knockoff.

There's a good chance I'll change that second line into 'draw a card'. Written this way, the card conveys draw step theft better, but I can't justify the inelegance of it unless I have a few cards like howling mine to make draw steps more significant. That said, I do intend on making cards along those lines (but then I am a little doubtful that I'll be able to pull them off).

Not sure about the templating; I was looking at wanderwine prophets, but I thought 'additional' sounded more appropriate than 'extra', as in paradox haze.

Also, I'm not sure about UU. This is slower than divination so it ought to be cheaper. But UU is a pretty big colour commitment. Then again, 1U seems too powerful, and completely eclipses fatigue. I'm leaning to UU because I figure this isn't a Limited turn-two play anyway, so it's not important that it work with the kind of aggressive curve that takes a mana cost of CC to be risky.

As this card is currently worded it would definately interact interestingly with cards like Howling Mine, Font of Mythos, Razormane Masticore, etc. The potential card draw of this card "as-is" is huge for a common, even at .

I certainly think that Fatigue with the cantrip rider is the better way to go though I would make it an Uncommon for .

Alternately, you could go with a replacement effect... "The next time target player would draw one or more cards, you draw that many cards instead". Not specifically draw step theft but blanket draw theft instead.

Your replacement effect suggestion is quite a bit better than what I have here. Do you think that could stay at common? What if I limited it to just one draw rather than 'one or more cards'? My instinct says that 'one or more cards', though considerably more interesting, has too much swingy-potential for common. I'd like to keep this one common; I see myself running out of room in blue uncommon.

Yeah, the one or more is definately not common, but as it is now I think its fine at common. It is an interesting variation but as its a sorcery its not overly powerful.

A nice common version of Plagiarize (which also proves that your instinct was correct that the one-or-more version was not common).

Cool, 11 more blue commons to go.

I'd forgotten about Plagiarize. I didn't anticipate that kind of templating. Can 'you draw a card instead' do the same job as 'instead that player skips that draw and you draw a card'?

Yeah, it'll do exactly the same. I'm not sure why Plagiarize was templated like that; probably just to make it very clearly spelled out.

Cool, thanks for clearing it up.

Shouldn't it have a 'this turn' or 'until end of turn' clause?

Right you are.
